Technical Parameters
Alumina ceramic part Industry insulator dry pressing 1-8holes 95% alumina ceramic bar for band heater
Talc porcelain is made of mineral talc (3mgo.4siO2.H2O) as the main raw material, adding appropriate amount of clay and BaTi03 and other ingredients through the mixing process of grinding, molding and high-temperature sintering.
The main crystal phase of talc porcelain is primary pyroxene, namely magnesium metasilicate (chemical formula is Mgsio3), which is a kind of high-frequency structure ceramic with excellent electrical performance and low price. It is often used as an insulating part in high-frequency equipment.
